Driveway
Track segment driveway straight
From the magnetic cuircuit point of view the driveway is comparable with the driveway of the Demonstrators. To make sure the given aims
- * Weight reduction
- * Reduction of the required constr. height
- * Cost reduction
- * Adaptability to any driveway courses
can be reached, nevertheless, it was necessary to rework the construction completely. It resulted in plane, module-like, easy addable track segments which are adaptable geometrically with little expenditure to the special requirements of the driveway course.
Drive
Actuation of the vehicle is implemented by means of a three-phase current-asynchronous linear motor in short stator arrangement whose primary part is fastened at the bottom of the vehicle. The accompanying secondary part is arranged as a reaction rail along the driveway.
The drive control occurs from the vehicle. The drive concept allows simultaneous and independent operation of multiple vehicles on the driveway.
Energy supply
The energy supply of the vehicle is realised by an inductive transference system which is integrated in the driveway and transfers the energy required for operation continuously towards the vehicle. For this purpose easy mountable line conductors are fixed to the driveway, feeding the energy via the air gap to a collector located in the vehicle.
Arrangement energy supply
Control system
The supervision and if necessary influencing of driving data relevant for security belongs to the duties of the control sytem, e.g.
- Detection of position and direction of travel (see Sketch)
- Observance of allowed maximum speeds of the vehicle or the track segment
- Reaction to the driving behaviour of other vehicles
For the vehicle control of SupraTrans II between two operation modes can be chosen:
- Automatic operation: In this mode enables an operating of the vehicle without driver.
- Manual driving mode: Control of the vehicle by a vehicle driver within the scope of the track parameters and track segments released by the control system
